This poster will highlight a series of project based activities carried
out at Hammond Elementary School in Laurel, Maryland, USA. All of the
featured projects revolve around the school's Green School Initiative or
an integral part of the science curricula. The Maryland Green
School program was developed by a diverse team of educators representing
the Maryland Association for Environmental and

(MAEOE), Office of the Governor, the Maryland Association of Student
Councils, Maryland Department of Education, Department of Natural
Resources and Maryland Department of the Environment. The program is
administered through the Maryland Association for Environmental and
Outdoor Education. The Maryland Green Schools Award Program recognizes
Maryland schools that include environmental education in the curricula,
model best management practices at the school and address community
environmental issues. Among these numerous projects water is a
common thread. Hammond Elementary School lies within the Chesapeake Bay
watershed which stretches across 64,000 square miles and encompasses the
entire District of Columbia. Educational components address habitats,
tributaries and, the estuary system. The projects being highlighted in
the poster will include: Trout to Streams Project: This 4th grade
project focuses on the natural filtration system that area trout provide
to the local and global waterways. As students learn about the
importance of various fish to the watershed, they come to understand the
effect of changes in the population of fish species due to consumption
and pollution. The service learning project highlighted teaches
students about water quality as they raise trout eggs and monitor their
development into hatching and later stream release. Buffer
Streams Tree Planting Projects: This 5th grade science service learning
project allows students to investigate the water quality and conditions
of local area streams. This project teaches students the positive and
negative effects of human presence on the local and global water supply.
Student research scientifically tested ways to slow down the effects of
run-off contaminants. Students also revisit water analysis and plant
trees as buffers as part of their stream preservation efforts in a
culminating activity. Oyster Reef Restoration Project: As a result
of changes in climate, pollution and human consumption, the oyster
population in the Chesapeake Bay had previously been on a rapid decline.
The Oyster Reef Restoration Project allows students to understand the
creatures of the bay and the cause of this decline. They explore the
domino effect this has had on the quality of the water in the bay and
future implications on the environment when the oyster population
fluctuates significantly. Students construct concrete reefs and study
the components of its contents and the reef's impact on the bay.
Students are responsible for mixing, pouring and preparing the reef for
its eventual drop in the bay. Wetlands Recovery: Following the
elimination of a substantial amount of the natural wetlands behind the
elementary and middle schools, a wetlands area was erected on the school
grounds. This pond has been used to learn about habitats and the role
humans, plants and organisms play in the preservation of the earth soil
and water supply. This wetland is used by both the elementary and
middle schools as a place for hands-on inquiry based learning. Students
maintain the upkeep of the pond and teach other students at lower
grades.
